A 10×10 ft (3×3 m) room typically needs 24–48 tiles, focused on the first reflection points around the listening position.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eWhat's the difference between 4″ (10cm) and 6″ (15cm)?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e4″ handles speech, vocals, and high-mids — best for podcasts and voice. 6″ reaches into the low-mid bass band (down to ~125 Hz) — choose it for drum rooms, mix rooms, and any space where bass build-up is a problem.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eDoes this soundproof my room from neighbors?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003eNo — and no acoustic foam does. Foam controls echo *inside* the room (absorption). Stopping sound from leaving the room is *soundproofing* and requires mass: drywall, mass-loaded vinyl, decoupled walls. KK1471 will not stop your neighbor from hearing your drums; it will make your drums sound dramatically better inside the room.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs the foam fire-safe?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003eYes. KK1471 is Class B fire-retardant and self-extinguishing — it will not sustain flame after the ignition source is removed. Always follow local building codes when installing on commercial or rental properties.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eHow do I install it without damaging my walls?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003eUse removable 3M Command strips or peelable adhesive squares. They hold the tiles firmly and remove cleanly when you move out. Avoid permanent spray adhesive on rented walls.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eHow long does shipping take?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003eHandling: 1–2 business days.

Use a sharp utility knife or electric carving knife. Cut on a flat surface with a straightedge. Pyramid tops can be trimmed flush for tight corners.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eWill the color fade?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003ePolyurethane foam will yellow over years if exposed to direct sunlight or strong UV. For rooms with windows, the Black and Gray options hold their color best.

The trade-off: those brands have larger US distribution and faster local replacements; KK1471 ships from our US warehouse but offers the 100-day guarantee instead.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs it safe around kids and pets?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003eYes — the foam is non-toxic.
